My Right arm was a major tear, Had Key hole Surgery by Dr Hitchen,
They grind the bone and trim the ligament, then screw 4 metal anchors
into the bone and stitch the ligament to the anchors,
It has to form a blood supply from the bone to the ligament to be successful.
6 weeks in a sling, sleeping was the major problem. The pain is constant
never seems to go away, need pain killers to sleep but not too bad during the day
If I tore it again I would have no hesitation in getting it repaired again.
They don't fix themselves they only get worse.
